It is a top view which showed the closed state at the time of use of the packaging container with a lid | cover shown in FIG. 12, Comprising: It is a figure corresponding to FIG. 5 of 1st Embodiment. It is the top view which showed the closed state at the time of use of the conventional packaging container with a lid | cover. It is the figure seen from the XV-XV line shown in FIG.

  FIG. 1 is a plan view showing an open state of a packaging container with a lid according to a first embodiment of the present invention, and FIG. 2 is a view taken along the line II-II shown in FIG. 3 is an end view of the III-III line shown in FIG.

  Referring to these drawings, the packaging container 1 with a lid is formed by integrally forming a single sheet of polyethylene terephthalate (PET) having a thickness of 0.35 mm, and the upper part is opened. The container body 11 having a substantially regular octagonal shape in plan view with the upper edge 15 rounded at the corner, and the container body 11 fitted to the container body 11 via the hinge portion 13 so as to be openable and closable. It consists of a substantially regular octagonal lid 12.

  If comprised in this way, since the container main body 11 and the cover body 12 will be connected integrally, the container main body 11 and the cover body 12 will not isolate | separate, but the reliability of a container will improve.

  The container body 11 is formed with a first tab 21 extending outward from the two-dot chain line portion shown in FIG. 1 of the upper edge 15 of the container body 11 at a position facing the hinge portion 13. A second tab 22 that extends outward from the lower edge 16 and overlaps the first tab 21 when the container body 11 and the lid body 12 are fitted is formed.

  The first tab 21 has a substantially constant distance with respect to the two-dot chain line portion shown in FIG. 1 of the upper edge 15 so as to span from the one end 23 to the other end 24 in the direction along the container body 11. First perforations 31 are formed. The second tab 22 is formed with a second perforation 32 that overlaps the first perforation 31 when the container body 11 and the lid body 12 are fitted together. The effect of having such a configuration will be described later. In addition, the 1st perforation 31 and the 2nd perforation 32 are formed on the extension line of the lower edge 16 of the cover body 12, and are linear form in planar view.

  FIG. 4 is an enlarged view of the “X” portion shown in FIG.

  Referring to the drawing, the first perforation 31 includes a notch 34 formed at one end 23 of the first tab 21 and a plurality of cuts 35 each having a width set to 2.0 mm. And starts from one end 23 of the first tab 21. An interval a between the notch 34 and the cut 35 closest to the one end 23 is set to 1.5 mm, and an interval b between the cuts 35 is set to 1.0 mm. Note that the second perforation (not shown) is also formed on the second tab (not shown) so as to overlap the first perforation 31 with the same configuration as the first perforation 31.

  If comprised in this way, since resistance at the time of the cutting | disconnection start by the side of the one end part 23 will become large, the possibility of the unnecessary cutting | disconnection of a perforation is reduced.

  5 is a plan view showing a closed state when the lidded packaging container shown in FIG. 1 is used, FIG. 6 is a view seen from the VI-VI line shown in FIG. 5, and FIG. FIG. 8 is an end view of the VII-VII line shown in FIG. 5, FIG. 8 is an enlarged view of the “Y” portion shown in FIG. 7, and FIG. 9 is a plan view from the packaging container with a lid shown in FIG. It is the top view which showed the state which removed the 1 tab and the 2nd tab.

  First, referring to FIG. 5 to FIG. 8, in the lidded packaging container 1, the lid body 12 is fitted into the container body 11, and the first tab 21 and the second tab 22 are subjected to ultrasonic welding. It is in a closed state in a state where it is integrated at the outer portion of the first perforation 31 and the second perforation 32 through the welded portion 25 generated by the application.

  When the first tab 21 and the second tab 22 are pulled in the direction of the arrow in FIG. 5 in this state, the first perforation 31 and the second perforation 32 are formed to overlap as described above. Will be cut off together.

  Then, referring to FIG. 8 and FIG. 9, as the first perforation 31 and the second perforation 32 are cut, the welded portions 25 of the first tab 21 and the second tab 22 are attached to the lidded packaging container. Therefore, the lid 12 can be opened and closed. The lid 12 is opened and closed by picking a knob 19 that is knurled.

  If comprised in this way, the closed state until the time of opening will be stabilized, and the reliability of the packaging container 1 with a lid will improve.

  FIG. 10 is a plan view showing an open state of the lidded packaging container according to the second embodiment of the present invention, corresponding to FIG. 1 of the first embodiment, and FIG. It is a top view which showed the closed state at the time of use of the packaging container with a lid | cover shown in FIG. 10, Comprising: It is a figure corresponding to FIG. 5 of 1st Embodiment.

  In the first embodiment, since the first perforation and the second perforation are formed in a straight line, the first tab is located at the overlapping position of the first perforation and the second perforation. And the 2nd tab tends to bend and there exists a possibility of inadvertent cutting | disconnection by vibration etc.

  Therefore, referring to these drawings, the first tab 21 is formed so as to straddle the side facing the hinge portion 13 of the upper edge 15 of the container body 11 and the other side adjacent to the side, Each of the second tabs 22 is replaced with one formed so as to straddle the side facing the hinge portion 13 of the lower edge 16 of the lid 12 and the other side adjacent to the side. Note that, as described above, the first perforation 31 corresponds to the two-dot chain line portion shown in FIG. 10 of the upper edge 15 so as to span from the one end 23 to the other end 24 in the direction along the container body 11. The second perforation 32 and the second perforation 32 overlap the first perforation 31 when the container body 11 and the lid body 12 are fitted to each other. Since each of the first perforation 31 and the second perforation 32 is formed on an extension line of the lower edge 16 of the lid body 12, the shape of the first perforation 31 and the second perforation 32 is a straight line as shown by a two-dot chain line in FIG. 11. It is not a thing, but it is a thing bent in the middle. Since other parts are the same as those shown in FIGS. 1 and 5, the description thereof will not be repeated here.

  If comprised in this way, the bending rigidity of the 1st tab 21 and the 2nd tab 22 in the whole overlap position of the 1st perforation 31 and the 2nd perforation 32 will increase, and it will be careless by vibration etc. The risk of cutting is reduced.

  FIG. 12 is a plan view showing an open state of the lidded packaging container according to the third embodiment of the present invention, corresponding to FIG. 1 of the first embodiment, and FIG. It is a top view which showed the closed state at the time of use of the packaging container with a lid | cover shown in FIG. 12, Comprising: It is a figure corresponding to FIG. 5 of 1st Embodiment.

  With reference to these drawings, the upper edge 15 of the container body 11 and the lower edge 16 of the lid body 12 are replaced with a substantially circular shape in plan view. Note that, as described above, the first perforation 31 corresponds to the two-dot chain line portion shown in FIG. 12 of the upper edge 15 so as to span from the one end 23 to the other end 24 in the direction along the container body 11. The second perforation 32 and the second perforation 32 overlap the first perforation 31 when the container body 11 and the lid body 12 are fitted to each other. Since each is formed on the extended line of the lower edge 16 of the lid body 12, the shape in plan view is not a straight line as shown by a two-dot chain line in FIG. 13, but a curved line. Since other parts are the same as those shown in FIGS. 1 and 5, the description thereof will not be repeated here.

  If comprised in this way, the bending rigidity of the 1st tab 21 and the 2nd tab 22 in the whole overlap position of the 1st perforation 31 and the 2nd perforation 32 will increase, and it will be careless by vibration etc. The risk of cutting is reduced.
